STRAIGHTERLINE NUTRITION FINAL EXAM
PREP 2026-2027 QUESTIONS AND CORRECT
ANSWERS GRADED A+
Fall in blood glucose during exercise is related to the depletion of ____ glycogen
liver (not muscle0
____ glycogen is used to maintain blood glucose
liver
what is the main fuel for prolonged low-intensity activity
fat
for lengthy activities at a moderate pace, fat supplies how much of the energy
required?
70-90%
The only fast-paced anaerobic fuel we eat is
carbohydrate
,Slow and steady aerobid activity uses___ in addition to ___
fat/carbohydrateq
amino acids derived from protein only supply about ___ of the body's general
energy needs.
5%. 10-15% during endurance exercise.
the primary muscle fuels for weightlifting are
PCr and carbohydrate for the brief bursts of energy, and fat during the resting
states
Is it possible to increase muscle mass by eating protein?
No. Physical strain/strength training is needed.
Estimated calories to sustain moderate activity
5-8 kcal/minute
Recommended carbohydrate intake for athletes
60% or more
,Three major causes of fatigue in athletes
depletion of fluid; depletion of electrolytes, and depletion of carbohydrates
carbohydrate loading
high carbohydrate intake is consumed for 6 days before an athletic event while
tapering exercise duration in an attempt to increase muscle glycogen stores.
The amount of activity would be for events lasting more than 60-90 minutes so it
applies to relatively few athletes.
Purpose of carbohydrate loading
to increase muscle glycogen stores by 50-85% over typical conditions.
disadvantage of carbohydrate loading
additional water (about 3 grams) is incorporated into the muscles along with each
gram of glycogen. Additional water weight and muscle stiffness can detract from
sports performance.
consuming carbs ___ a competition provides about the same advantage as carb
loading
during
, fat needs for athletes
up to 35% of calories from fat
protein needs for athletes
1.0 - 1.6 grams of protein per kg of body weight.
protein needs for non athletes
.8 grams per kg of body weight
heat exhaustion
The first stage of heat-related illness that occurs because of depletion of blood
volume from fuluid loss by the body. This increases body temperature and can lead
to headache, dizziness, muscle weakness, and visual disturbances etc.
heat crams
A frequent complication of heat exhaustion. They usually occur in people who
have experienced large sweat losses from exercising for several hours in a hot
climate and have consumed a large volume of water. The cramps occur in skeletal
muscles and consist of contractions for 1 to 3 minutes at a time.
heat stroke
